To all whom it may concern Be it'lrnown that if, (learns Roan, a citizen of the United States, and residing at Astoria, L. 1., in the county of Queens and State of New York, have invented certain new and useful Improvements in ToeLSupporting Spindles, for Woodworking Machines, of which the iollowi-ng is a, specification, such as will enable those skilled in the art to which it apperitains .to make and use the same.

. This invention relates to woodworking machines and particularly to the tool supporting spindles thereof, and the object of the invention .is to provide an improved spindle of this class which is so constructed as to permit of the mounting of a number of cutter blades in connectiontherewith, and

the cutting edges of which extend radially from the axis of said spindle; a further object being to provide means mounted on the spindle and located between the separate cutterblades, thereof for. reinforcing said cutter blades; a further object being to pro vide means for temporarily retaining said cutter blades in predetermined positions; a furtherobject being to provide means whereby accidental detachment of the cutter blades from the spindle is obviated; .a still further object being to provide means for retaining said cutter blades and other parts in predetermined position; and with these and other objects in view the invention cone sists in a tool supporting spindle of the class and for the purpose specified which is simple in construction,efiicient in use and which is constructed hereinafter described and claimed. 1

The inventionis .fully disclosed in the following specification, of which the accompanying drawing forms a. .part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which- 1;-

Fig. l is aside view of my improved spindle showing a number of cutter blades mounted in connection therewith with parts of the construction broken away and in section;

Fig. 5 a perspective detail view or". one of anumber of cutter blades or tools; and,

6 a detail view showing a modificat on.

in the drawing 1 have shown at 10 my improved spindle provided at its opposite ends with suitable shanks 11 to permit of its mounting in a woodworking or other turn ng machine, and the spindle 10 is .threaded throughout its entire length and 1s provlded at" the opposite end portions ,thereof'with twosets of radial apertures .12 and l3, each set of apertures crossing through the axis of the spindle at right angles, and the separate sets of apertures being spaced apart centrally of the spindle as shown at 14.

By providing the two sets of apertures, I may mount a number of cutter blades or tools 15, one of which is shown in Fig, 5 of the drawing, in connection with the spindle 10 to extend radially therefrom in four difvjlferent positions ninety degrees to each other, and these blades or tools are preferably mounted to extend alternately ninety degrees apart front-the spindle to form of all of the blades or tools mounted in connection w th the sp ndle, a spiral arrangement or formation on the spindle, this will be clearly understood on a consideration of Fig. 1 in which the first tool mounted in connection with the left hand end portion of the spindle is directed back-wardly, the next tool is directed upwardly, the next tool is directed forwardly and the next tool is directed downwardly, etc. I

In Fig. l of the drawing. l have shown four tools or blades 15 mounted in connection with the set of apertures 12, while three tools or blades are shown mounted in con nection with the apertures 13.

The opposite side edges of the tools or blades 15 are provided with recesses 16 whereby when the separate blades are mounted in the sets of apertures l2-l3, the adjacent or abutting edge-s thereof are interlocked one with another to prevent the movement of said blades radially from the spindle inv the event of the loosening of the securing means for such blades or tools. The method of interlocking the separate blades or tools .is-clearly shown in Fig. of the drawing, It will be'noted that the relie to bring the cutting edges 17 of the blades or tools in proper position.

, I also employ a number of reinforcing and spacing rings 18, one of which is shown in detail Fig. 1- of the drawing, and these rings are located between the abutting edges on opposite side faces with notches or recesses adapted to receive the shanks of sa d blades or tools to reinforce the project- I portions of said blades or tools, as will be apparent. The periphery of the rings 18 l -o serve to form stops for the workpiece feeding the wood strip toward the blades or tools of the spindle in order to limit the depth of the cut in such workpiece. I also employ a number of set screws 20 which are adapted to operate in connection with the blades or tools and retain the same in predetermined positions of adjustment in as seirbling or mounting the tools in connection with the spindle, and I also employ two nuts 21'and 22 which are in threaded engagement with the spindle 10 and are provided for the purpose of retaining all of the blades or tools 15 as well as the rings 18 in predetermined positions.

In 1 of the drawing, 1 have shown two sets of the nuts 21 and 22, one set being adapted to hold the blades or tools 15 and 18 that are mounted inthe apertureslZ in position, while the other set of said nuts retain the blades or tools and rings in the apertures 13. of the spindle.

in assembling the blades or tools in the spindle. one of said blades or tools is placed in one of the apertures 12 and retained in the desired position of adjustment by the setscrew 2O cooperating with said blade, a Titer which one of the rings 18 is mounted in po. ion, to engage said blade and another blade placed in position and at right angles to the first named blade and retained in position by the set screw for said blade,

after which, another of the rings 18 is mounted in position and this operation is repeated until the desired number of blades have been mounted in the apertures 12 of the spindle, after which the nuts 21 and 22 moved into operativeposition to firmly retain the blades and rings in position and a washer 23 is preferably employed between the out 21 and blade or tool adjacent thereto, and if it be desired the blades 15 and rinaslS may also be mounted in the apertures .13 of spindle in the same. manner and retained in. position by the other set of nuts 21 and 22, and a washer 28 will also be employed as shown in Fig. 1.

It will be apparent that when seven of the tools are mounted in connection with the spindle, as shown in Fig. 1, a comparatively wide molding or other workpiece strip is to be operated upon and the cutter blades or tools will be so positioned on the spindle to cut a predetermined contour in the workpiece or strip as indicated in dot and dash lines in Fig. 1 of the drawing. It will be understood thatany number of the tools may be employed and said tools may be mounted in connection with either set of apertures 1213 and may be secured in posi tion in any desired manner. Byproviding the set screws 20, as shown in the drawing, they may also serve for the purposeof retainingbalancing slugs in connection with p the spindle, in which event, the slugs will be mounted between the heads ofsaid screws and the periphery of'the spindle but, in view of the method of mounting the cutter blades or tools in connection with the spindle it may be found to be unnecessary to do this. It will also be apparent on a considera tion of Fig. 1 of the drawing that the toolor blade adjacent to the nuts 21 and 22 may extend over the, periphery of the nuts as shown at 15 in Fig. 1 of the drawing to cut the workpiece at this point but this is'not absolutely necessary.

It will also be noted that the cutting edges of the tools employed are preferably turned slightly in the direction of the plain face of the tool as shown at 15 in Fig. 2 of the drawing to facilitate the operation of cutting a predetermined contour in a work piece.

It will be apparent that while I have shown certain details of construction for carrying; my invention into effect that I am not necessarily limited to these details, and

various changes in and modifications of the construction herein shown and described may be made, within the scope of'the appended claims, without departing from the spirit of my invention or sacrificingfits advantages. V

In 6 of the drawing I have shown a part of one'of the spacing rings 18 and have shown a slight modification in the form of said ring in which the periphery or outer face of therine is cut away. as shown at .185 at one side'of oneor more of the recesses 19in said rind so that the. operation of the tools .15. the shavinus of the workpiece may fall nto the cut away portion 18 of the rings 18. l

it will also be understood that where the rings 18 serve as stop members for limitins: the inward movement of the work iece that the tools or cutter blades 15. or the cutting edges 15 thereof are practically flush with the periphery of said stop rings 18 or onlv project slightly therefrom.
